To all whom it may concern.

Be it known that we, Cnursrornnu VF. CAREY and Crinsrnn S. Lnoninn),citizens of the United States, residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have ointly invented certainnew and useful Improvements in Apparatus for Displaying AdvertisingMatter, of which the following is a specification.

This invention has relation to apparatus for displaying advertisingmatter, wherein at predeterminedintervals, an electromagnet is energizedby the closing of a circuit to permit to operate a motor, which in turnrevolves carrier for consecutively displaying advertising cards andrefers more particularly to the apparatus described and claimed inUnited States Letters Patent, N o. 805,786, and dated November 28, 1905.

It has been demonstrated in practice, it is essential among otherthings, to the commercial value of the apparatus above referred to, thata perfect circuit-closer be present for periodically completing and.breaking the circuit through the electromagnet. It has also been proven,that it is essential to energize the electro-magnct in advance of theoperating of the motor, which drives the carrier containing the displaycards. Practice has also demonstrated, that it is detrimental to theapparatus to revolve the carrier rapidly and suddenly stop its movement.Considerable diiliculty has also been experienced in securing a carrierfor the display cards of such construction that the cards be centralizedwith respect tothe carrier during movement thereof in contra-distinctionfrom being moved laterally or sidewise, thereby jamming.

It is one object of the present invention to overcome the above reciteddisadvair tageous features and to provide apparatus that is reliable inoperation and comparatively inexpensive to manufacture.

A further object of the present invention resides in the providing of acircuit-closer of cam-like construction with which cooperates a gravitycontact.

A further object of the present invention resides in the providing of aspecially de signed contact so arranged and constructed that themechanical-electric motor for operating the chain of display cards beper mitted to operate only after the electro-magnet has been energizedand the transmission medium be released for operating.

A still further object of the present invention resides in the providingof a specially designed carrier for a chain of advcrtising cards of suchconstruction that the individual cards in moving are maintainedcentrally of the carrier in contra-distinction from moving sidewisethereon and j annning.

Other objects of the present invention resides in the novel arrangementand construction of parts which are particularly de signed for theout-door display of advertising cards and in so arranging the parts thatready access may be had thereto for interchangeable connection of thevarious devices.

lVith these and other objects in view, the invention consists of theimprovements hereinafter described and finally claimed.

The nature, characteristic featln'es and scope of the invention will bemore fully understood from the following description taken in connectionwith the accompanying drawings, forming part hereof and in which:

Figure 1, is a perspective view of the advertising apparatus embodyingthe invention, Fig. 2, is a view in front elevation, with certain of thecasing parts removed, illustrating the interior arrangement of theapparatus, Fig. 3, is a view in elevation, drawn to an enlarged scale,of the clock movement shown at the lefthand side of Fig. 2, Fig. at, isa perspective view of the circuit-closer shown in Fig. 3, F ig. 5, is aview in elevation of the side of the circuit-closer opposite to thatshown in Fig. 3, Fig. 6, is a view in front elevation of the carrier forsupporting the chain of advertising cards shown in Fig. 2, Fig. 7, is aview in section taken upon the line 7--7 of Fig. 6, Fig. 8, is a top orplan view of the carrier operating mechanism shown at the right-handside of Fig. 2, Fig. 9, is a view in section taken upon the line 99 ofFig. 8, and Fig. 10, is a fragmentary view, in elevation, of certain ofthe parts shown in Fig. 9, but in a different position.

The advertising apparatus, about to be described, is primarily intendedfor outdoor display and to that end, practice has demonstrated thatspecially designed parts are essential to the successful operation ofthe apparatus. As shown in Fig. 1, the casing 1, is preferably of sheetmetal construction. Such a structure is practical for out-- door use andpreserves the contents of the casing against attack by the elements. Thecasing 1, is shown as being comparatively narrow in comparison to itsheight and as being provided with hinged covers 2, and 3, at suitableplaces. The casing 1, is further provided with a time piece 4, andpreferably an incandescent lamp and reflector 5, for illuminating theface thereof. Immediately below the time piece, the casing 1, isprovided with an opening 6, before which are calculated to appear thevarious individual cards, bearing advertisements, which go to make upthe endless chain of cards 7, see Fig. 2. Above the opening 6, isarranged a reflector 8, preferably containing incandescent lamps forilluminating the cards as they appear before the opening 6. Taking upnow the parts within the casing 1, the card operating mechanism is shownas being located well toward the top of the casing and immediately backof the time piece 4-. Supported upon suitable brackets 9, is ahorizontally disposed plate 10, see Figs. 2, 8, and 9. As shown in Fig.8, this plate 10, is centrally cut-away as at 11, to accommodate therotatable carrier 12. The rotatable carrier 12, is arranged centrally ofthe plate 10, and is journaled thereto as at 13, so that in itsrotation, the endless chain of cards 7, passes in the direction of thearrow, see Fig. 2, up through the opening 11, of the plate 10. As shownin Fig. 2, an electric mo tor A, is presentupon the plate 10, adjacentthe right-hand side of the carrier 12, which electric motor isoperatively connected through the instrumentality of a transmissionmedium B, with said carrier. Shown at the left-hand side of the carrier12, and as being supported by the plate 10, is a clock movement 0.Mounted upon a moving part of the clock movement is a circuitcloser forperiodically completing and breaking a circuit through an electro-magnetfor alternately releasing and stopping the transmission mediumindependently of the starting and stopping of the electric motor.

A description will first be given of the circuit-closer, reference beinghad more particularly to Figs. 1, to 5, inclusive. The shaft 14:, of theclock movement 0, which shaft is operative through the instrumentalityof the pendulum 15, in connection with the weight 15 ms fixed theretothe circuit-closer 16, of the invention, which in operation moves in thedirection of the arrow in Figs. 3, and 4E. The circuit-closer 16, whichis cam-like in construction, is shown as comprising a pair of disksarranged side by side upon the shaft 1 1, and as being adj ustablyconnected together concentrically considered as at 17, see Fig. 5. Ofthese two disks, the disk 18, is of insulating material, preferablyfiber, and the disk 19, is of conducting material, preferably brass. Theperipheries of the disks 18, and 19, in effect form a cam face. Havingpivotal relation as at 20, with the frame of the clock movement C, is agravity contact strip 21. As clearly shown in Fig. the pivotal point 20,of this contact strip is arranged in a plane considerably above that ofthe highest point of the circuit-closer 16, so that the contact member21, through gravity rests upon some part of the cam face of saidcircuit-closer at all times. The contact strip 21, as shown in Fig. at,is of a width equal to the width of the combined parts 18, and 19. Theparts 18, and 19, are cut-away as at 22, and 23, to provide a step downarrangement for the gravity contact strip, of which the part- 22, of thedisk 18, is arranged in advance of the part 28, of the disk 19. Thus, inrotation of the circuit-closer 16, in the direction of the ar row inFigs. 3, and 4, the contact strip 21, normally rests upon the disk 18,of insulated material during which time the motor A and transmissionmedium E, are inoperative. hen the high portion of the disk 18, leavesthe free end of the contact strip 21, said contact strip gravitates toand rests upon the high part 2 1, of the disk 19, and remains in contacttherewith for a period of time in proportion to the adjustment securedby the parts 17, see Fig. 5. The contacting of the contact strip 21,with the disk 19, energizes the electro-magnet D, from batteries 26,through conductor 25, to shaft 1%, disk 19, contact strip 21, conductor27, to electro-magnet D, the return circuit being by conductor 28, tobatteries 26.

The energizing of the electro-magnet D, releases mechanism about to bedescribed for permitting to operate the transmission medium B. In thisconnection it will be noted that the electro-magnet is energizedinnependently of and considerably in advance of the energizing of theelectric motor A. Referring now more particularly to Figs. 8, 9, and 10,said transmission medium E, is shown as being supported between .uitableuprights 29. Shown as having pivotal re lation between and insulatedfrom the uprights 29, is a bar 30. Having fixed rela tion with the bar30, as at 31, is a forwardly extending metallic rod 82, the free end ofwhich terminates in a depending generally hook-like extension 33, thepurpose of which will presently appear. This rod 32, carries a block ofinsulating material 3%, extending laterally from which is a metallic pinAlso fixed to the pivotal bar 30, is an armature 86, which isalternately caused to advance toward or recede from the electromagnet D,as the magnet is energized or deenergized. In order to properly supportthe free end of the rod 32, the same is connected by means of a rod 37,with, but insulated from the armature 36. Shown as mounted upon one ofthe uprights 29, is a contact strip 33, which is insulated therefrom andlaterally extending so as to overlie the rod 32. Leading from thebatteries 39, to the pivotal. bar 30, is a conductor 40, and lead ingfrom the contact strip 33, to one pole of the electric motor A, is aconductor 41, the opposite pole of the electric motor A, being connectedby a return lead 42 to the batteries 39. The batteries 26, and 39, arearranged in multiple series, as such arrangement is particularly adaptedfor the operation of applicants devices. The transmission medium B,which is directly influenced by the above described connections, isprimarily made up of a series of intermeshing wheels of such dimensionsthat they cooperate to transmit a suitable speed to the shaft 4L3, towhich is fixed the carrier 12. These intermeshing wheels in turn aredivided into two groups, one group for directly operating the shaft 43,and the other group for operating a speed governor 4.4., which speedgovernor is permitted to operate by the raising of the end 33, of therod Taking up now the first series of wheels the shaft 45, is providedwith a cog wheel 46, and gear wheel 47. The gear wheel 4L7, meshes withthe cog wheel 48, of the electric motor A, see Fig. 8. The gear wheel47, serves to operate a train of gear wheels connecting with thegovernor i l. In turn, the cog wheel 46, meshes with a gear wheel 49,mounted upon a shaft 50. The shaft 50, has secured thereto an escapementwheel 51, notched as at 52, to correspond with the number of cardreceiving faces upon the carrier 12, four being shown in the drawings.The direction of rotation of the escapement wheel 51, is in thedirection of the arrow in Fig. 9, and the hereinbefore described pin 35,carried by the rod 32, normally rests within one of the notches 52, ofsaid escapement wheel. In this position the rod 32, is free of andlocated below the contact strip 33. When a contact is made between thedisk 19, of the circuitcloser 16, and the gravity contact member 21, toenergize the electro-magnet D, the rod 32, is moved around its pivotalpoint by virtue of the armature 36, being drawn toward the electromagnet D, which movement raises the pin 35, from its complemental notch52, of the escapement wheel At the same time a contact is made betweenthe rod 32, and contact strip 33, which contact energizes the electricmotor A, through conductor 41, and sets in operation the above describedsets of gear wheels and through the instrumentality of gear wheel 53,which is in mesh with the gear wheel 49, sets in motion the shaft 43,together with the carrier 12. By referring now to Fig. 10, it will beseen that during the above operation the pin 35, rides upon theperiphery of the escapement wheel 51. As the pin 35, rides upon theperiphery of the escapement wheel, the rod 32, cannot gravitate but isheld in constant contact with the strip 33. Thus, as the movement of thecircuit-closer 16, is relatively slow, a long contact is maintainedbetween the batteries and the electro-magnet D, and a continuance ofcurrent is furnished the electric motor A, by reason of the escapementwheel in contra-distinction to a short quick current supply. Thus, asure and positive operation of the electric motor A, insures an accurateand steady movement of the carrier 12. As the next succeeding notch ofthe escapement wheel, comes in alinement with the pin 35, the rod 32,gravitates, thereby breaking electrical connection between the parts.

A description of the retarding wheels of the transmission medium B, willnow be given. The shaft 54, has a cog wheel 55, which meshes with thebefore described gear wheel 47. This shaft 5st, in turn is provided witha gear wheel 56, which meshes with a cog wheel 57, on a shaft 58. Theshaft 58, in turn is provided with a gear wheel 59, meshing with a cogwheel 60, on the shaft 61, which carries and has fixed thereto, thespeed governor 44. When the electromagnet I), is energized, therebyraising the rod 32, the end 33, of said rod is moved free of the speedgovernor a l, permitting it to move in the direction of the arrow inFig. 9, through the instrumentality of the last-i'nentioned intermeshingwheels. When the electromagnet l), is deenergized the motor A, continuesto operate so long as the pin 35, is in engagen'ient with the peripheryof the disk 51. When, iowever, one of the notches 52, of said disk comesopposite the pin 35, said pin drops therein, whereupon the rod 32,gravitates to its normal position, electrical connection to the motor isbroken and it stops, and the governor H, abuts against the end 33, ofthe rod 32, thus effectually stopping any momentum of the transmissionmedium E, as a whole.

Taking up now the carrier 12, which is fixed to the shaft 43, the sameis shown as comprising a pair of end plates 62, connected together bymeans of horizontally extending rods 63. These rods penetrate the plates62, and may be secured thereto by means of screws 6%, see Fig. 8. Eachend plate 62, is of circular configuration, generally speaking, and isprovided on its inner face with a generally rectangular member forming aledge 65, for supporting the chain of cards 7. In the drawings, thefaces of the ledge 65, are four in number. Between each card receivingface 65, and the peripheries of the end plates a generally convenedsurface 66, is present and between the ledges 65, and the plate centers,a spider-like construction 67, is present, in order to provide lightnessof structure. In practice, the generally curved.

surfaces 66, serve to guide the cards of the chain '7, toward the centerof the carrier. In other words the curved surfaces 66, of the plates 62,prevent the cards from shifting endwise so as to create a jamming of thecarrier parts.
